OPTICAL TRANSMISSION/RECEPTION DEVICE, OPTICAL COMMUNICATION SYSTEM AND OPTICAL TRANSMISSION/RECEPTION METHOD

摘要

Even in a case where light sources at an optical transmission-side and an optical reception-side are made into a common light source, a optical transmission function and an optical reception function are enabled to be used at a time.;An optical transmission/reception device according to the present invention includes optical split means for splitting the light from the optical output means into a first split light and a second split light, optical power adjustment means for respectively adjusting the optical power of the first split light and the optical power of the second split light, optical transmission means for modulating the first split light whose optical power is adjusted, and outputting the modulated first split light as a first optical signal, optical reception means for receiving the second split light whose optical power is adjusted and a second optical signal given from an outside by causing the second split light and the second optical signal to be interfered with each other, and control means for controlling the optical power adjustment means in accordance with an optical property of the output light.
